What Is Hypertension And How Is It Controlled?
Hypertension, an abnormally high arterial blood pressure, if left unattended, can cause many
health problems including stroke and heart attack. Hypertension can be controlled by altering
one’s lifestyle, avoiding stress, and with medication under a doctor’s supervision.
To prevent hypertension or to keep it under control:
• Do not smoke
• Exercise regularly
• Reduce salt and fat intake
• Have regular physical checkups
• Maintain proper weight
Why Measure Blood Pressure At Home?
Blood pressure measured at a clinic or doctor’s office may cause apprehension and can produce
an elevated reading, 25 to 30 mmHg higher than that measured at home. Home measurement
reduces the effects of outside influences on blood pressure readings, supplements the doctor’s
readings and provides a more accurate, complete blood pressure history.
WHO Blood Pressure Classification
Standards to assess high blood pressure, without regard to age, have been established by the
World Health Organization (WHO), as shown in the chart below.
